Seeing Life in 4K throughSXRD Technology
Cassidy YoungSenior Product ManagerDigital Cinema Solutions
What are we talking about with 4K?• 4K can be many formats
– 4096 x 2160 is the imager size @ 1.89 aspect ratio– 3996 x 2160 is what’s projected for flat presentation– 4096 x 1714 is what’s projected for scope presentation– 3840 x 2160 is what’s projected for HD
